![]() “The one thing I liked about this project was being able to create something that works out of everyday materials,” Rivas said. In the upcoming weeks, the students will continue to test their catapults for accuracy and make changes to the their catapults to see how it affects the data that they collect. “During the testing phase I learned that our catapult had some strengths and weaknesses to it, and while it only took us one day to build it, we did have to financial and make some changes to it,” Rivas said. Students were given two or three days to build their catapult and work on the PowerPoint that goes along with the project. If the requirements were not quite met in testing, students could go back and change the design. The catapult is made by gluing three popsicle sticks together and then using rubber bands to connect the popsicle sticks. A popsicle stick catapult is a type of catapult that can be made out of popsicle sticks, hot glue, bottle caps, and rubber bands. “It launched a bouncy ball more than 1.5 meters.” How to make a catapult with popsicle sticks. “Ours was able to meet all the requirements,” Rivas said. They made sure it could launch the ball more than 1.5 meters, and that the projectile would land near the same point on repeated launches. ![]() “We got many of our ideas from Pinterest as well.”Īfter students made their catapults, they put them through a series of tests. “We used a binder clip, pencil, plastic spoons, and some rubber bands,” junior Karina Rivas said. They can use popsicle sticks, rubber bands, wood, hot glue, and other objects to make sure that their catapults launch properly. The catapult can be made out of any materials that allow it to work. Students must make a catapult that can launch a bounce ball to a distance of more than 1.5 meters. They are making the catapults as part of their current studies, the projectile motion unit. Cross’ physics class are building catapults this week. My 17 year old is a little stumped.The students in Mrs. We're not looking to plagiarize but if anyone has tackled this project with success, I could use a few ideas. The V-shaped gap created by the two sticks should hold the stack securely in place. Place the popsicle stick with the cap on top. Slide another popsicle stick between the bottom-most stick in the pile and the rest of the stacked sticks, perpendicular to the pile. ![]() Stack 6-8 popsicle sticks on top of one another and secure both ends with rubber bands. Gently separate the two craft sticks, and push the stack of 7 craft sticks through them. Directions: Glue the plastic cap to one end of one popsicle stick. Now it’s time to connect the base and launching stick. Press down on the spoon gently while holding the bottom of the catapult with your other hand. Pull apart the 2 popsicle sticks and wedge the stack of 7 between those 2. We've looked for ideas on the net but have not found anything this small with that type of performance. Step 4: Connecting the Base and Launching Stick. Stack the popsicle stick with the spoon and another popsicle stick and tie one end with a rubber band. The little catapult will need significant speed on the launching arm to achieve that distance and misplaced finger could suffer injury which would result in possible disqualification. That much energy starts to encroach on the safety aspect of the unit. It will take a considerable amount of stored energy in a very small catapult to reach a distance of 30 feet. We went to Kroger last night and naturally got the biggest tissue box they had and it's dimensions are 8 1/2" X 4 1/4" X 4 1/4". Total money to be spent on the project is $10 or less. Place one additional jewel in the center of one of the smaller sticks (this stick will go on top). ![]() Then use a glue gun to add jewels to the ends of each stick. Next, paint a layer of glitter paint on the top and the sides of each stick. ![]() The parameters of the project are that the catapult must be no bigger than a tissue box and must be able to SAFELY launch a tennis ball a distance of 30 feet in the air. Lay the sticks flat and let them dry completely. We have a junior in high school who has an extra credit project. ![]()
